      <h1>Data Quality Measures (DQM) Version: 1.0</h1><img src="dqm.png"><h2>Description</h2>
      <p>DQM 1.0 is an XML Schema implementation derived from ISO ISO 19157, Geographic Information - Data Quality, Clause 6.5.  It includes elements for describing data quality measures. The XML schema was encoded using the rules described in ISO/TS 19139:2007, Clause 8 and implementation approach from ISO/TS19115-3, Clause
         8.
